net/mlx4: Adapt code for N-Port VF
Adds support for N-Port VFs, this includes:
1. Adding support in the wrapped FW command
In wrapped commands, we need to verify and convert
the slave's port into the real physical port.
Furthermore, when sending the response back to the slave,
a reverse conversion should be made.
2. Adjusting sqpn for QP1 para-virtualization
The slave assumes that sqpn is used for QP1 communication.
If the slave is assigned to a port != (first port), we need
to adjust the sqpn that will direct its QP1 packets into the
correct endpoint.
3. Adjusting gid[5] to modify the port for raw ethernet
In B0 steering, gid[5] contains the port. It needs
to be adjusted into the physical port.
4. Adjusting number of ports in the query / ports caps in the FW commands
When a slave queries the hardware, it needs to view only
the physical ports it's assigned to.
5. Adjusting the sched_qp according to the port number
The QP port is encoded in the sched_qp, thus in modify_qp we need
to encode the correct port in sched_qp.

Joe Perches provides patches for e100, igb, igbvf, ixgbe and ixgbevf to

Don provides two fixes for ixgbe, first resolves a link issue with DA
cables where we were not always freeing the firmware/software semaphore
after grabbing it. Second stops caching whether the management firmware
was enabled, however since this is not static, we really need to verify

Jacob provides six fixes/cleanups for ixgbe, most notably, correct
the stop_mac_link_on d3() to check the Core Clock Disable bit before
stopping link and to fully check to see if manage firmware is running or
could be enabled before bringing down the link. Fix flow control
auto-negation for KR/KX/K4 interfaces, since setting up MAC link, the
cached autoc value and current autoc value were being incorrectly used to
determine whether link reset is required.
Emil provides a fix for ixgbe where there was a chance for aggressive

queues to after the link is established.

functions. Likewise we weren't always freeing the FWSW semaphore after
grabbing it. This would lead to DA cables being unable to link along with
possible other errors.

Intel Wired LAN Driver Updates
This series contains updates to i40e, i40evf, e1000e, ixgbe and ixgbevf.
Mitch adds support for the VF link state ndo which allows the PF driver
to control the virtual link state of the VF devices. Added
support for viewing and modifying RSS hash options and RSS hash look-up
table programming through ethtool for i40evf. Fixed complaint about
the use of min() where min_t() should be used in i40evf.
Anjali adds support for ethtool -k option for NTUPLE control for i40e.
Elizabeth cleans up and refactors i40e_open() to separate out the VSI
code into its own i40e_vsi_open().
Jesse enables the hardware feature head write back to avoid updating the
descriptor ring by marking each descriptor with a DD bit and instead
writes a memory location with an update to where the driver should clean
up to in i40e and i40evf. Reduces context descriptors for i40e/i40evf
since we do not need context descriptors for every packet, only for
TSO or timesync.
Dan Carpenter fixes a potential array underflow in i40e_vc_process_vf_msg().
Dave fixes an e1000e hardware unit hang where the check for pending Tx work
when link is lost was mistakenly moved to be done only when link is first
detected to be lost. Fixed a problem with poor network performance on
certain silicon in e1000e when configured for 100M HDX performance.
Carolyn adds register defines needed for time sync functions and the code
to call the updated defines.
Jacob adds the ixgbe function for writing PCI config word and checks
whether the adapter has been removed first.
Mark adds the bit __IXGBEVF_REMOVING to indicate that the module is being
removed because the __IXGBEVF_DOWN bit had been overloaded for this
purpose, but leads to trouble. ixgbevf_down function can now prevent
multiple executions by doing test_and_set_bit on __IXGBEVF_DOWN.
v2:
- dropped patch Mitch's patch "i40evf: Support RSS option in ethtool"
based on feedback from Ben Hutchings so that Mitch can re-work the
patch solution
v3:
- removed unnecessary parenthesis in patch 1 based on feedback from David
Miller
- changed a macro to get the next queue to a function in patch 2 based on
feedback from David Miller
- added blank lines after variable declaration and code in two functions

One patch to rename a newly introduced struct. The rest is

support inter address family tunneling and namespace crossing.
1) Rename the newly introduced struct xfrm_filter to avoid a
conflict with iproute2. From Nicolas Dichtel.
2) Introduce xfrm_input_afinfo to access the address family
dependent tunnel callback functions properly.
3) Add and use a IPsec protocol multiplexer for ipv6.
4) Remove dst_entry caching. vti can lookup multiple different
dst entries, dependent of the configured xfrm states. Therefore
it does not make to cache a dst_entry.
5) Remove caching of flow informations. vti6 does not use the the
tunnel endpoint addresses to do route and xfrm lookups.
6) Update the vti6 to use its own receive hook.
7) Remove the now unused xfrm_tunnel_notifier. This was used from vti

8) Support inter address family tunneling for vti6.
9) Check if the tunnel endpoints of the xfrm state and the vti interface
are matching and return an error otherwise.
10) Enable namespace crossing for vti devices.

Altera Triple Speed Ethernet (TSE) Driver
This is the version 6 submission for the Altera Triple Speed Ethernet (TSE)
driver. All comments received during the version 2, 3, 4, and 5 submissions
have been accepted. Please find the change log and a description of the
submission below.
If you find the submission acceptable, please consider this patch set for
inclusion into the Linux kernel.
V6: Address comments from V5 review
- add call to skb_tx_timestamp in the drivers transmit path
- correct use of unsigned int where it was cast to pointer. Use types
appropriate for intended and correct use to let the compiler warn us
when type usage is incorrect.
- use correct semantics for pointer arithmetic in same code path
V5: Address comments from V4 review
- Add descriptions of statistics to driver documentation. The statstics
supported by the driver/controller map to IEEE and RFC statistics, and
the names and mappings are described in the user documentation.
- Change "unsigned int" to u32 in device structure definitions
- Change used of netdev_warn to netif_warn in altera_sgdma.c
- Change stat name rx_fifo_drops to ether_drops to match the event
actually counted by the hardware.
V4: Address comments from V3 review
- Change statistics names in ethtool module to follow common use in
other ethernet drivers.
- remove an unnecessary case in ethtool module
- change logging to use netdev_* where possible instead of dev_*
- remove logging for OOM errors since those are already logged
V3: Address comments from V2 review
- Reorder patch submission so that net/ethernet Makefile and Kconfig
are committed last, thus not breaking bisect
- Use of_get_mac_address instead of of_get_property
- Change supplemental and hash configuration bindings to boolean/empty,
and more meaningful names
- Add check for failure from calls to of_phy_connect and
connect_local_phy
- Correct code to find mdio child node
- Update bindings document
- Remove cast to u64 when not necessary
- add use of const for statistics strings
V2: Address comments from initial RFC review.
- The driver files were broken up by major sections of functionality.
These include MSGDMA, SGDMA, Misc, and Main.
- Add patch for MAINTAINERS file, add the maintainer for this submission
- Use 32-bit lower/upper physical address accessor functions so the driver
is 64-bit ready.
- Use standard bindings where applicable. Especially phy-addr, and change
"altr,rx-fifo-depth" to "rx-fifo-depth" and "altr,tx-fifo-depth" to
"tx-fifo-depth".
- Add use of max-frame-size property
- Update bindings documents accordingly
- Correct interrupt handler to use budget parameter in the convential way
- Use macros consistently to define bit fields across files
- Correct include exclusion macro in altera_msgdmahw.h (typo)
- Remove use of barriers, these were not necessary since the DMA APIs
ensure memory & buffer consistency
- Remove use of netif_carrier_off in driver
- move probing of phy from the open function to the probe function
- use of_get_phy_mode instead of custom function
- Use the .data field in the device structure to obtain a pointer
to SGDMA or MSGDMA device specific properties and functions.
- remove custom function to access devicetree since Altera specific
bindings requiring it's use have been deprecated in favor of
standard bindings.
The Altera TSE is a 10/100/1000 Mbps Ethernet soft IP component that can be
configured and synthesized using Quartus, and programmed into Altera FPGAs.
Two types of soft DMA IP components are supported by this driver - the Altera
SGDMA and the MSGDMA. The MSGDMA DMA component is preferred over the SGDMA,
since the SGDMA will be deprecated in favor of the MSGDMA. Software supporting
both is provided for customers still using the SGDMA and to demonstrate how
multiple types of DMA engines may be supported by the TSE driver in the event
customers wish to develop their own custom soft DMA engine for particular
applications.
The design has been tested on Altera's Cyclone 4, 5, and Cyclone 5 SOC
development kits using an ARM A9 processor and an Altera NIOS2 processor.
Differences in CPU/DMA coherency management and address alignment are
addressed by proper use of driver APIs and semantics.

While checkpatch another patch I got a:
"WARNING: msleep < 20ms can sleep for up to 20ms"
The datasheet of at86rf231 and at86rf212 says a minimum delay for reset
pulse width and spi access latency after reset is 625 nanoseconds.
This patch removes the 1 milliseconds sleep and replace it with a 1
microseconds udelay which should be also okay for the reset pulse width.
To change the state from RESET -> TRX_OFF the at86rf230 device needs 120
microseconds, this is a worst case of all at86rf* chips.

netpoll: Cleanup received packet processing
This is the long-winded, careful, and polite version of removing the netpoll

First I untangle the code in small steps. Then I modify the code to not
force reception and dropping of packets when we are transmiting a packet
with netpoll. Finally I move all of the packet reception under
CONFIG_NETPOLL_TRAP and delete CONFIG_NETPOLL_TRAP.
If someone wants to do a stable backport of these patches, it would
require backporting the first 18 patches that handle the budget == 0 in
the networking drivers, and the first 6 of these patches.
If anyone wants to resurrect netpoll packet reception someday it should
just be a matter of reverting the last patch.
